Be it known thatl, OTTO KARTZMARK, a

' citizen of the United States, residing atNVest Haven, in the county of New Haven and I 5 State of Connecticut, have invented certain new and useful Improvements in Dispensing Receptacles, of "which the following is a .specification Y.

. This invention relates to receptacles or 1 storage retainers from which any suitable commodity such'ascoal, grain, sand,'lime,

groceries, or. other loose bulk articlesare adapted to be. dispensed from the bottom, and whilethis'device has been constructed 5 and has been successfully used for the purpose oftemporary storage and dispensing of;

.coal for a kitchen range or the like in dwelling houses, I/wish it to be understood that it is'capable'of a much wider'range' of usefulness asnthe title indicates r Among the objects ofthe invention is to provide a; receptacle of the natureindicated having ,apeculiarly.arranged hopper bottom g and delivery chute, the construction of which renders it especially well adapted for the delivery of the last particle of material, the

provision ,of a closure ,or door having new and peculiar co-operation with the chute portion ofthe hopper bottom whereby the closure, is free-to swingthrough substan-.

tiallyaaquarter-of a circle aroundits hori zonta-l pivot or axis so asto lie lopenfor .shoveling purposes or to-be self retained in [closed position, due to itsgover weight in either, position, butwhich is easily swung from'either position to the otherby ato'uch j from the operators hand or foot, and which also is'of such a nature as tofprevent the. dischargej'of dust or dirt from the recep-l ,tacleto the floor or any other ,p artof the building, and the. construction furthermore has reference tofafnumber of details of con structio'n'which tendto simplify, strengthen,

and improve the device forfpractical pur- 455 poses. I

,With the foregoing and other objects in ','view' the invention consists in the arrange Q ment and cornblnationo'f partsherelnafter b described and claimed, and while the inven ftion is not restricted to the exact detailsof' construction disclosed or suggested herein,

Supporting casters for these legs purpose. 7

The main hopper bottom comprises a construction made from the blank of Figs 7 and includes a main rear panel 24-, two side wings '25, two front wings 26, and a sub stantially horizontal front plate 2f. The

side wings 25 are bent-at an obtuse angle Y forming a delivery opening 32 of triangular ,form over and spaced from the plate 21.

and through which the commodity to be dis :pensedwill naturally flow orroll bygrav ity upon the plate 27. V-Vhile this plate is approximately horizontal it is indicated in downwardslightly toward the front to fa- 'cilitate the delivery of the goods.

- The chute portion of the bottom ismade preferably froma. blank or pattern as shown in Fig. 8 and comprisesa top panel and.

.two side panels 34, the latter being con- 'nected to the top panel along parallel bending lines 35; Thistop panel therefore is substantially rectangular'but for a triangular notch 36 cut from tsrear end and registering with the delivery open ng 32 above describedp ln other words, theover- "lappingfront wings26 of the main bottom member substantially coincide with the remaining top portion 33 of the chute. This makesan exceedingly-strong and'rigid chute the triangular side panels 34 are bent in-* eonstructionand;with no possibility for any of the material jor -dust to be discharged laterally therefrom. =The bottom edges of ardt wed a h o he 3 a above? ti enper-rsurtace f; th ang 3 is secured the plate v27', said flanges being the front, having a horizontal portion and two upright portions whose upper ends are secured at 39 to the bottom rail 16 of the front wall 10. This yoke is strong and rigid and directly embraces the front ends or edges of the side panels 34, and upon the upper surface of the yoke is supportedthe front end or edge of the plate 27.

, g The closure comprises a rectangular front plate 40 with two parallel side wings 41' of substantially quarter circle form. The front or upper edge of the plate 40 strikes against'the front portion of the just mentioned rail 16 while the side wing-shave loose embracing engagement with the sides of the yoke 38, and the lower edge of the plate 40 rests or rolls like a knife edge upon the front end of the plate 27. Thus the closure opens and closes with. practically no friction and this constant contact between the two plates 27 and 40 prevents any dust or other material from passing forward under the closure. Any suitable means may be provided to prevent the displacement of the closure from the yoke. As shown this means comprises a pair of ears'42 'formed'on the corner portions of the yoke, the upper free ends of which ears are bendable rearward toward the main portions of the side bars of the yoke forming eyes 43. Said ears are projectable through holes L4 formed in the lower corners of the plate, these holes as well as the eyes 43 being large enough to insurefree swinging movement of the closure ineither direction. From the normal closed position, as shown in Fig. 3, the closure may beswung fordownward upon a lug d5 fixed near thebottom thereof. Thus the closureis swung forward until it passes the dead center and is finally stopped by a lug 46 formed at the upper rear end of either wing ll which strikes against the bent portion 39- ofthe.

yoke. See Fig. 4. To close the chute the ward by any suitable means, as 'bybearing operator has but to lift easily upon theplate 4C0 causing it to swing'till stopped by striking the rail 16 as already stated. 7

From the foregoing specific -description ofthe mechanism illustrated its mode of op,-,

,eration may be briefly summed upas, follows Thev closure, plate 40 being normally shut as in Fig. the receptacle may betilled through the opening at the top after the. lid 14 [is lifted, afportion of the f cioal or. other materialrollingoi' flowing ward through :the registering openings I 32 @136. are? pl fioor 27 f the chute but" "at no time pushing forward against the closure forcibly enough to open the closure. For removing the material through the chute the operator drops the closure plate downward, as shown in Figs. 1 and 2, and over this plate the shovel or the like may be operated rearward beneath the bulk of material upon the" plate 27, the shovel being readily filled thereby and removable over the closure. Anyloose particles of the material dropping from the shovel will'bereceived upon the plate 27 or plate 40 and between the Wings 41 thereof. After theloperation is completed the closure is lifted and the wings thereof swinging rearward beyond the vertical plane of the axis constituted by the lower edge of the plate 40 pass freely. along the outer sides of the chute walls 34 and wings connected thereto, means being p-ro-- vided to attach the closure to the chute structure for movement of theclosure around a horizontal axis indirect contact withsaid plate. i

2. A device as set forth in claim 1 in which the front mouth portion of the chute includes a-reinforcing yoke and the means for attaching the closure for swinging movement includes members formed as said yoke.

3. A receptacle as set forth in claim 1 in parts 'of which there is provided a reinforcing frame for the mouth of the chute and the closure is connected to said frame for swinging around a horizontal axis, and stop means is provided acting between the closure and the frame for limiting the forward swing of the closure into open position.

4. In a dispensing receptacle, the combination of a bottom structure including a plate and a chute, a] reinforcing frame bounding the mouth portion of the chute, the front end of the bottom plate'resting upon the frame, the frame being provided with a pair of ears adjacent to said bottom plate, and a closure for the chute comprising a plate portion whose lower corners are interengaged with said ears and whose lower edge bears consequently upon the upper'surface of the plate.

5. A receptacleas set forth in claim 4 in which the closure includes a pair of parallel side wings each of substantially quarter circle form and having'stop means at the rear corner thereof to limit the swing ofthe closure. -6.'A receptacle as set-forth in claim 4 in I which the closure includes a pair of side wings of arc-shape and of a radius shorter than the height of the closure plate, the portion of the plate extending above the side wingsstriking rearward against the main structure to limit the swing thereof 'rear5 Ward.

7. In a dispensing receptacle, thecombr' nation with a main body, of a hopper bottom structure therefor including two triangular shaped front wings arranged in substantially the same plane but with por forward v tions thereof overlapping forming a dis-' charge opening through the hopper bottom,

and a chute extension below said opening, said chute extension including a top panel and sidewings, said top panel having a re cess coextensive and registering with the opening aforesaid in the hopper bottom.

8. A receptacle as set forth in claim 7 in which the hopperbottomstructure includes a plate extending forward of and below the discharge opening and upon which the maf terial is received through said opening, and

the chute structure includes side panels co operating with the side edges of said plate extension. v

9. A receptacle of the nature set forth in- I cluding a substantially rectangular body portion, supporting legs for. said body, each leg'having a substantially vertical portion of rectangular form in cross section and having at its upper end two angle'members extending horizontally and diverging from each other at a right angle forming a seat for the adjacent corner of the body, the weight of the body coming directly upon the flanged structure of the legs.

10. A receptacle of the nature set forth including a substantially rectangular body portion, supporting legs for said body, each legcomposed of two angle members assem- 'bledto form a rectangular portion while the upper ends diverge from eachother at right angles and with two vertical and two horizontal flanges, the vertical flanges being on the outside of the corner portion of the body v supported and embraced thereby.
